Company Overview

The Walkie Talkie building (20 Fenchurch Street, London) A comprehensive range of systems using Radmat’s PermaQuik, ParaFlex and EshaUniversal roofing membranes have been installed during the creation of the Landmark building, which includes a breathtaking ‘Sky Garden’ – one of the highest green roofs in the world.Architects: Raphael Viñoly

Bloomberg European HQ building uses PermaQuik’s Hot Melt Monolithic Waterproofing System; PQ6100, PQ2017, PQ2060/61, an ideal solution as it combined excellent waterproofing performance with toughness, durability, flexibility and strong adhesion to a variety of substrates including zero falls.

PermaQuik will last the design life of the structure

Many architects and clients have sought Radmat’s well-known technical expertise in waterproofing solutions, leading to PermaQuik being specified for:

• Government buildings where exceptional reliability and longevity are key considerations, e.g. GCHQ Cheltenham, MOD Whitehall, The Treasury, City Hall, Scottish Parliament, The Home Office

• PFI hospitals and schools where long-term performance is a fundamental requirement for underpinning the client’s 30 year-plus responsibilities for building performance

6

The new Library of Birmingham installation used PermaQuik PQ6100 Hot Melt Monolithic waterproofing system, set to deliver exceptional performance befitting of the uniquely designed structure which has set a remarkably high standard for library design.

GCHQ building, CheltenhamBeneath the central green roof at GCHQ, PermaQuik was specified to provide a lifetime of waterproofing security.

A roofing solution that is BBA Certified to last ‘the life of the building’

Company Overview

PermaQuik has been specified and used on a number of public buildings such as the Library of Birmingham (above) and the GCHQ buiding (below).

PermaQuik has also been used for schools and academies, and been independently assessed for performance and durability. This type of independent certification is of considerable benefit, and never more so than for the Building Schools for Future programme. Their documented recommendations state that the roof coverings should be independently certified to have a minimum life of 30 years.

7

Used extensively on and around the higher terrace and over the many podium levels, PermaQuik was the waterproofing choice for Olympic Village, London.

Crossrail Place, Canary WharfExtensive and densely planted gardens are the main feature in the roof terrace above the Cross Rail terminal, shops and restaurants. PermaQuik was the waterproofing choice of contractors Prater Ltd.

Blue and Green roof systems that provide first-class performance

Company Overview

PermaQuik is regularly used as the waterproofing protection beneath permanent features such as green roofs. Our system has been accredited to last the lifetime of the structure; it is fully adhered, can self heal and is widely used in zero fall applications and within water retaining structures. Very few systems provide such credentials, and these attributes should always be considered a necessity when waterproofing beneath substrates that will be extremely costly to remove.

Working in conjunction with trained horticulturists, Radmat provides a wide range of systems, from standard hand-seeded biodiverse roof gardens to options with immediate visual effect such as wildflower or sedum roof blankets.

Notable Contracts

Used extensively on and around the higher terrace and over the many podium levels, PermaQuik was the waterproofing choice for City Hall, London.

Why PermaQuik? Radmat has been at the forefront of the expansion of hot melt technology in Europe for the past 15 years, and in North America for the last 40 years. At Radmat we frequently work with architects, clients, main contractors, and our approved contractor network, to improve the quality of our offer. This has led to a huge growth in the use of hot melts technology. Working closely with Shell UK, Radmat have developed a blended bitumen that is workable at considerably lower temperatures, and has reduced packaging to minimise any excess site waste.

Whilst many companies may look to copy the Radmat formula, many will not succeed. Given the importance of a watertight building, PermaQuik will always be the proven solution.

ProductionThe PermaQuik 6100 monolithic membrane and its associated products are fully certified for quality. With manufacturing bases for PermaQuik in Ontario Canada, and Lancashire England, we have the ability to supply our products quickly and efficiently to a worldwide list of clients. Within each region we have looked to gain independent accreditation for our products and processes. In the United Kingdom PermaQuik is independently approved by the British Board of Agrément (BBA), certificate No. 97/3336, and is now coming to its fifth issue. The certificate states that once installed PermaQuik will continue to perform and remain weathertight for the design life of the structure to which it is applied.

Radmat Support

Radmat offers extensive technical support at all stages of the construction process, enabling the development of appropriate and efficient design solutions for a wide range of building projects.

We are committed to make available first-class materials, installed by an approved list of contractors and agree designs that are both practical and cost effective.

Detailed DesignAssistance with detailed design includes: • CAD drawings • Condensation analysis • Hydraulic resistance • Wind loadings and uplift • Drainage fall/dispersal calculations • NBS format specifications

Tender DocumentationRadmat can assist with the compilation of roofing tender documentation for each building project, will provide a list of roofing contractors approved for the system and can also provide realistic cost advice at project planning stage installed PermaQuik will continue to perform and remain weathertight for the design life of the structure to which it is applied. Within Canada, PermaQuik is approved by the Canadian Government specification board (CGSB) under 37-GP-50M Standard for ‘Hot applied rubberised asphalt for roofing and waterproofing’.

Approved ContractorsThe PermaQuik system is installed by a national network of Radmat contractors. These specialist trade contractors are trained and frequently monitored by Radmat technical personnel to maintain the high quality of service expected. During the design stage we either provide technical drawings and calculations for the contractors or we review and sign-off their details to ensure all elements of the build are fully checked.

Site VisitsWe provide on-site assessment of the installation process, firstly to determine that the substrate is acceptable and thereafter to ensure that the application of PermaQuik 6100 is carried out correctly and in line with our recommendations.

WarrantyAfter the acceptable completion of the works, and following an independent electronic test, we will issue either a Standard or 35 year Gold single source workmanship and materials warranty.

Data SheetsProduct, health and safety and material data sheets are available from Radmat on request or can be downloaded from our website at www.radmat.com.

PermaQuik 6100 monolithic membrane roofing system is a one part, hot applied, seamless rubberised self-healing membrane made from bitumen, natural rubbers, and a blend of polymers, further reinforced with a high tensile polyester fabric. This mix combines excellent waterproofing performance with toughness, flexibility, and strong adhesion to a variety of substrates.

The membrane joins to form a fully sealed monolithic bond when areas of previously laid PermaQuik are lapped with new hot material. This allows the upstands to be installed first, giving other trades the ability to swiftly progress with the fabric of the building. It also enables work to stop and start as required without affecting the quality of the finished membrane. PermaQuik will even self-heal minor damage and is also designed to accept a high degree of structural movement.

PermaQuik provides the main waterproofing protection to any number of building types. Routinely specified as the preferred roofing solution, it is widely used beneath green roof installations, on ground floor plazas and in areas where long term weather tightness is a necessity.

PermaQuik can be installed to site working temperatures of -18°C and after installation the membrane will immediately remain unaffected by rain, wind or snow. PermaQuik has been independently certified by the BBA to perform on a zero falls construction and has a durability statement of lifetime of structure.

Seamless monolithic bond

System Overview

Offers long-term protection under roof gardens

11

Benefits• Quick and straightforward to apply

• Completely seamless to form a monolithic bond

• Water cannot track under the membrane – therefore enabling any damage to be traced quickly and easily repaired

• Adheres readily to any sound concrete, brickwork, timber or steel, and will effectively cover corners and any minor surface irregularities or protrusions

• Can be applied in temperatures down to -18ºC (unlike conventional bitumen/asphalt membranes which require temperatures above freezing

• Excellent low-temperature flexibility and adhesion characteristics

• No on-site curing time required

• When used over construction or bridging joints, without the need for specific detailing, the membrane is flexible enough to accommodate minor structural movements that are likely to occur

• Membrane interleaved with a reinforcement sheet gives triple protection to flashings/penetrations

• Once covered with a protection sheet, the waterproofed area can be immediately opened up to following trades

• Will self heal minor damage under applied loads

• Membrane functions efficiently when applied to roofs with zero falls

• Membrane has been independently assessed to last the lifetime of the structure.

The mixed-use development of Principal Place, comprising of a 15-storey office building (home to Amazon HQ) 20,000 square foot of retail space and a 50-storey luxury residential tower, used PermaQuik extensively throughout the development because of its durabliity for the brown and green roofs.

System Overview

Typical working surface

Sweep to remove debris

Apply Radmat Surface Conditioner

Although roof areas will vary from project to project, a typical installation procedure for an inverted roof terrace is described below to illustrate the use of the PermaQuik system.

PermaQuik and Texsa Root Barrier are installed (right) on The Forge, London. This residentiial project is a mixture of Blue and Green Roofs, PermaQIk will ensure watertightness and durability to last the design life of the building.

System Installation

Suitable Substrates1. In situ structural concrete to BS 8110, density to be no less than

2100kg/m3 and with no more than 5% moisture by volume when fully cured after a period of 14-21 days. Concrete should be wood float, wood trowelled or a similar finish but not power floated or tamped.

2. Precast concrete (structural grade)

3. Dense concrete blocks

4. Metal, timber boarding, WBP or marine plywood

5. Cement-bonded particle board

6. High-strength modified screed

7. Foamglas cellular insulation

Concrete Substrate PreparationTypically, the cleaning of a concrete surface will commence with a thorough sweep of all dirt and construction debris and then cleaning with a blower. Do NOT power wash with water.

All concrete surfaces must be left dry, frost free, free of voids, laitance or any other matter that may impair the high bond or performance of the membrane. Contact Radmat for advice on the effective removal of more difficult contaminants such as form-release agents or curing compounds.

The resultant surface should be uniform and lightly roughened to increase the bond achieved by the membrane.

After cleaning and any necessary repair work the concrete substrate should be primed with Radmat Surface Conditioner, a high penetration primer, spray or roller applied at the rate of 7-12m2/litre. Allow the primer to dry thoroughly. Metal, plywood and wood boarding need not be primed.

13

Install first layer

Apply 1st layer in 1m wide bays.

Install reinforcement layer.

Install final layer with protection sheet.

Check thickness of system.

System Installation

ApplicationAfter the concrete substrate has been primed, heat the blocks of PermaQuik 6100 in a double-lined oil or air type melter to a temperature of 150°C - 180°C and mix slowly. The application of PermaQuik should not proceed during inclement weather and rain soaked surfaces should be thoroughly dry before the first layer is applied.

The membrane should be installed on all the vertical surfaces prior to application of the horizontal surfaces. Ensure that when applied the material is returned onto the flat by a minimum of 150mm. Using a squeegee apply the first layer of membrane to the main areas of the substrate to a minimum thickness of 3mm. Work to a bay size of approximate 1m wide but allow to extend this to accommodate the 75mm overlap.

Apply PermaQuik PQ2016 fleece reinforcement, overlapped by 75mm, and brush into the membrane. Ensure there are no air pockets or creases. On the same day apply a second coat of PermaQuik to a minimum thickness of 3mm fully encapsulating the fabric reinforcement within the membrane.

A Radmat protection sheet should then be brush-rolled into the membrane surface as quickly as possible while it is still tacky and warm. All protection sheet edges should overlap by a minimum 75mm and sealed with PermaQuik. Once installed the waterproofed area can be accessed by operatives to install the subsequent coverings.

TestingBefore the application of any insulation or covering materials the roof area should undergo either an electronic roof integrity test or a flood test. Any damaged areas will be highlighted and can be easily repaired. PermaQuik 6100 is a thermoplastic material, therefore the heat from the new material will reactivate the existing membrane to fuse both layers together, forming a monolithic barrier.

CoveringsAfter the successful application of the PermaQuik membrane it can either be left exposed, provided a suitable protection layer is incorporated, or covered by insulation and a variety of materials including our MedO range of green roof systems.
